Synthesis and Characterization of the Molybdenum Carbonyl‐Functionalized Zintl Ions [(η4‐Pb4)Mo(CO)3]4− and [Pb4{Mo(CO)3}3]6−

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 13, 1 September 2026.
The reaction of the tetrahedral [Pb4]4− with Mo(CO)4(tmeda) yields two different Mo(CO)3‐functionalized clusters which can both be related to known clusters by the same substitution pattern following the isolobal principle. The crystal structures of [Na([2.2.2]crypt)]2Na2[(η4‐Pb4)Mo(CO)3] · 8.7NH3 and Na6[Pb4{Mo(CO)3}3] · 22NH3 are reported.

Collisionless Shocks: Contemporary State After Three Quarters of a Century of Research

open access: yesReviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract The collisionless shock research started in the late 1950s. Since then, plenty of data have been accumulated due to the large number of missions in the heliosphere, providing in situ measurements of the fields and particles. The quality of these measurements has vastly improved, especially in the last two decades.

Personalization and Fortification of In‐Space Manufactured Emulsified Beverages for Long‐Term Space Travel

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT The current trend of individualized food items (nutrient content and flavor) can be particularly valuable to support people's health and well‐being in isolated environments where access to fresh foods and diverse nutrition is difficult. At the same time, bioactive compounds and micronutrients can be employed to countermeasure any health ...

Whole Genome Assembly and Annotation of Two Invasive Sitona Species

open access: yesJournal of Applied Entomology, Volume 150, Issue 8, Page 1025-1034, September 2026.
ABSTRACT Weevils are a highly diversified taxon, comprising about 70,000 described species, including many of high economic importance. Here, we present whole genome assemblies and annotations of two Sitona species (Coleoptera: Curculionidae: Entiminae).

Constraints on the generalized Chaplygin gas from supernovae observations

open access: yesPhysics Letters B, 2003
Exploramos las implicaciones de las observaciones de supernovas de tipo Ia (SNIa) en modelos cosmológicos planos cuyo contenido de materia es un fluido exótico con ecuación de estado, p=-M^(4(a +1))/rho^a. En este escenario, un solo componente fluido puede conducir al Universo de una fase dominada por la materia no relativista a una fase de expansión ...

INCORPORATING ASTROPHYSICAL SYSTEMATICS INTO A GENERALIZED LIKELIHOOD FOR COSMOLOGY WITH TYPE Ia SUPERNOVAE [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT Traditional cosmological inference using Type Ia supernovae (SNe Ia) have used stretch- and color-corrected fits of SN Ia light curves and assumed a resulting fiducial mean and symmetric intrinsic dispersion for the resulting relative luminosity.

Gravitational Radiation From Binary Systems With Time Varying Masses

open access: yesAnnalen der Physik, Volume 538, Issue 8, August 2026.
We extend the standard approach pioneered in the works by Peters and Mathews to include the mass loss processes of the binary components, by obtaining the variations due to gravitational radiation of the main physical parameters. As an application of our results we consider gravitational radiation emission in binary magnetar systems.

A MORE GENERAL MODEL FOR THE INTRINSIC SCATTER IN TYPE Ia SUPERNOVA DISTANCE MODULI [PDF]

open access: yesThe Astrophysical Journal, 2011
We describe a new formalism to fit the parameters $α$ and $β$ that are used in the SALT2 model to determine the standard magnitudes of Type Ia supernovae. The new formalism describes the intrinsic scatter in Type Ia supernovae by a covariance matrix in place of the single parameter normally used.
